Genes affected
ITPR1 (HGNC:6180): (inositol 1,4,5-trisphosphate receptor type 1) This gene encodes an intracellular receptor for inositol 1,4,5-trisphosphate. Upon stimulation by inositol 1,4,5-trisphosphate, this receptor mediates calcium release from the endoplasmic reticulum. Mutations in this gene cause spinocerebellar ataxia type 15, a disease associated with an heterogeneous group of cerebellar disorders. Multiple transcript variants have been identified for this gene.

Spinocerebellar ataxia type 29 Pathogenic:1
Pathogenic, no assertion criteria provided | research | Research Group Niklas Dahl, Uppsala University | Aug 01, 2016 | We have identified a biallelic (homozygous) missense mutation in ITPR1 segregating with an autosomal recessive and early onset cerebellar syndrome. Heterozygous individuals are asymptomatic albeit with unequivocal cerebellar hypoplasia. Our findings add to the genetic complexity of Spinocerebellar ataxia (SCA) and broaden the correlations between ITPR1 variants and their clinical expression. - |
